Conservation of Energy

Physics

The law of conservation of energy states that the total energy of an isolated system remains constant, meaning energy can be transformed from one form to another but cannot be created or destroyed.

  • Lead section (proposed-year)
    The principle was formulated in its general form by Hermann von Helmholtz in 1847, building on earlier work by Julius Robert von Mayer and James Prescott Joule.

  • Proposed By: Hermann von Helmholtz, Mechanical equivalent of heat section (edge: proposed-by, Helmholtz)
    In 1847, drawing on the earlier work of Joule, Sadi Carnot, and Emile Clapeyron, Hermann von Helmholtz arrived at conclusions similar to Grove's and published his theories in his book Uber die Erhaltung der Kraft (On the Conservation of Force, 1847).
